To all 11i/mm if may Col/eem.'

Be it known that we, RALPH H. Ymsnnn and STt'AnT (i. lm's. hoth citizensof the United States, residing at llall'way and Detroit.7 Count)v ofMaeonih and eonnt)v of `Waynrn respeetirely, State of Michigan, haveinvented a eertain new and useful Improvement in Starting and LightingrDe vices for lnternal-Comhnstion Engines. of whieh the following: is aspecification. reference being had therein to the areompany ingdrawings.

Uur present invention relates to eleetrieal starting andlightingequipment for antoniohiles or other motor vehieles- Thepartienlar object; of the invention is to provide a simpler and moreeomenient meehanism than those heretofore eoinmonliY employed; also onewhieh ean he pnt in piave more eonvenientlj.' and rapidly. Theequipment. embodying our invention is ol' the donhle unit type. but itmay in some instances he employed to take the plane ot' .single nnit.systems already installed or he nsed in vom hination with power plantsdesigned especially for use in connection with .single unit sets.

Our invention is employed vin connection with an engine having a erankease and a flywheel casing, the flywheel ol' the engine, being providedwith Igfear teeth for engagement` with a pinion on the end of thestarting motor shaft. We provide a member called a. lhase on whieh areplaced the startu ingr motor and generator and within which are locatedthe switch and a portion of the mechanism hy means of whieh engagementbetween the starting.: motor shalt and the flywheel is etlei'ted.ll'ithin the flywheel easirngr is plaeed a train of gears eonnecting thestartin; r motor shalt with the flywheel gear, and these gears, aremoved into and ont of mesh as required ln' a plunger or shaft whieh alsooperatesy the elef'trie switeh of the starting motor and whit-li extendsthrough the tlrwln'el enaing into the hase.

This eonstrnetion has the treat advantage that it ma)v he assi-milledand lined np with very little el'ort or skill. To do this. the generatorand startingr motor are plated on the hase. the hase is pol in plzee onthe eranlt ease. the .switeh plonger i thi! im sorted llionoh the rranhease and the gear and pinion. These are then seenred to the plunger andthe bolts. whieh hold the hase in place on the erank ease. are thentightened up. Other important features of our invention will be apparentfrom the followinegr description.

The invention will he fully understood trom the following descriptionwhen taken in eonneetion with the aeeompanying drawings, and the novelfeatures thereof will he pointed ont and elearl)Y defined in the claimsat the close of this specification.

In the drawings. Fig. 1 is a side elevation of a power plant for anautomobile inelndingr an internal eomlnistion engine, together with theflywheel easing`r therefor, to whieh is applied a .starting and lightingset` embodyingr our present invention.

Fig. 2 is a longitudinal vertical seetion of the startingr andliifhtiineIr ser.. the hase and a portion ofthe era nk ease and flywheeleasing.

Fig. il .shows the parts shown in Figure 2 in the position whieh theyoeenpy -inst as the gears are about to mesh.

Fig. 4 shows the parts in the position oeenpied when the starting switehhas been closed.

Fig. 5 is a view of the plunger assembly.

Referring now to thel drawings, at A is `shown the crank ease. at lt theflywheel casing and at C the engine cylinders. In general, these partsare of ordinary construction and form no part of our invention. At. 11is shown the starting motor and at 12 the generator. The hase isdesignated 13 and rests on a portion e of the crank ease.y being seem-edthereto hy two holts 1l and 15. At 1G (see Figs. 2, 3 and 4) are shownthe gear teeth on the flywheel.
